Max Flow tank possible rocket

[dark assasin]

Well I was ajusting the regulater position when I noiced the maxflow 68ci 4500 tank was loose so I twisted it on and thought nothing of it. I told my friend and he says I shouldn't get it filled without telling someone because he heard that a kid was getting his tank filled with the same problem and the tank shot off the reg, hit and killed his mother. Now I personally think the story is bogus but should I fill my tank anyways it feels tight enough now it can't even twist alittle

[Skoad]

there was a CO2 tank on a gun, a kid went to unscrew it and instead of unscrewing from the ASA the reg unscrewed from the tank, which was launched like a missle and killed some lady when it hit her in the head.

[afultz075]

Don't get it filled. As far as I know, all nitro tanks need either loctited or torqued onto their regs

[the larch]

uhm, yeah, I would get that loctited. reg shouldn't be "finger tight" into a tank with four thousand five hundred pounds pers square inch of pressure. (written out to express what 4500psi actually means)

[FlameboyC11]

Take it to an airsmith. I believe that tanks must be tightened to about 38 lbs (torque wrench). This could be done by a person, and it's not like the tank is being held on by just how much you tighten it, it has threads for a reason...

[dynastyfan]

well i have a nitro duck mega reg and tank ans the threads on the tank are a good size bigger than a regular tanks threads and i just screw the tank in and it seems fine to me but i still havn't been able to fill the tank yet though

[tony3]

Smart parts as far as I knows send the bottles and regs seperate, as long as you screw it on tight, have the proper oring in there, you'll be fine.

[Fatjon]

Smart parts sends maxflos regs and tanks seperate, because you shouldnt be twisting on the tank anyways. You dont have to unscrew it. If the tank is all the way on the threads with 4500psi behind it, it is not coming off that reg.

That story about the kid killing a laddy is ture... there was an article on it, and it made the news. Its really old news by now.

Heres what happened, the kid just turned ten so for his birthday he wanted to finally play paintball! So at the end of the day he was screwing out the tank not knowing he was actually screwing the reg off the tank. After he got off the reg out it "took off like a torpedo" and struck his own mother in the back of her head killing her instintly.


You can find it on www.pbstar.com

Anyway how sad is that, the kid killed his own mother on his birthday, and he was only ten. Thats the saddest thing ever. If I were that kid I would go completely insane and just never talk or do anything ever again.

To sum up:

1. Your friend wasn't BS'ing you, that story is true.

2. Your tank is dangerous right now. Make sure it has NO air in it, and get it loctited/torqued in place by an airsmith. Do NOT use, fill, or do anything with it other than bleed out the air without having it fixed.

I got a tank hydroed by a local fire station and apparently they didn't torque it down after filling I thought nothing of it because I assumed it was ok, I got to the field, screwed the tank on my gun and got the tank filled, was still all good, I only noticed the problem when I tried to unscrew it at about 200-300psi, the cylinder started to unscrew from the reg, I grabbed it by the reg and unscrewed it from there, then I stuck it on an ASA and drained it, grabbed some blue loctite, put 4-5 drops on the end of the threads (not the top) and screwed on the cylinder, put it in my box inside the car to dry and seal, went and got it filled, all was good.

Every store I have been to shows the fact that the Max Flo unscrews off the reg as a bonus or good feature of the bottle/reg combo. No one hase ever said it was a bad thing. I agree if there is 4500 psi behind it there is no way you could unscrew it off the reg.

I agree. If it's not a screw in tank, I don't think the reg needs to be torqued... I'm pretty sure you're not supposed to locktite regs either. My fiance has been using a Hyperflow reg/tank that's not loctited or torqued and we've had no problems

I agree if there is 4500 psi behind it there is no way you could unscrew it off the reg.

You'd be surprised. I've heard otherwise.

Coming from a scuba background....

The tank need not be loctited on. It is proper procedure just to torque the tank onto the reg.

Scuba valves are never loctited on nor is it reccomended.

Regs and valves are designed with enough thread and some sort of saftey releif so that if the tank twists off the o-ring it will start venting air.

There is a reason why loctite isnt used it negates the saftey feature. Either by clogging and sealing the pressure relief hole or sealing all the threads so that the tank wont start venting at a fast enough rate until the reg is completely off and becomes a rocket.

[sneakyhacker420]

the max-flo systems are just attached with grease and an o-ring

grease to prevent thread damage, and an o-ring to seal it off

if you unscrew it enough, the o-ring will blow out and vent the air from the release hole on the regulator stem

no worries, its meant to be like that, and no one's had a Smart Parts space shuttle just yet... if you're paranoid, take a strap wrench and tighten it on just a little extra so you cant unscrew it with your hands
